Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a method for realizing a virtual intelligent boundary wall in a UE4 engine, which comprises the following steps of:
s102, obtaining world coordinates of all pixel points of the boundary wall from a material ball of the boundary wall, and transmitting the world coordinates of preset points to the material ball in a blueprint.
Specifically, the world coordinates of each pixel point are acquired by a material ball of the boundary wall, and the world coordinates of the preset points are transmitted to the material ball in a blueprint.
And S104, calculating the distance values between the world coordinates of the preset points and the world coordinates of all the pixel points on the boundary wall in the material ball.
Specifically, a float4 type variable named TriggerPoint is declared as the location of the trigger boundary wall preset point. And obtaining the world coordinates of each pixel point in the material ball, further subtracting the world coordinates of TriggerPoint, and calculating the size of each obtained vector, namely the distance value from each pixel point to a preset point.
And S106, when the distance value between the world coordinate of any pixel point in the boundary wall and the world coordinate of the preset point is smaller than the maximum distance value, displaying any pixel point in the boundary wall so as to display a circular area in the boundary wall.
Specifically, the distance is used to trigger the display of the boundary wall. And when the preset point is close to the boundary wall to the maximum display distance, displaying a pixel point of a circular area of the boundary wall, wherein the circle center position of the circular area is the position of the coordinate projection of the preset point on the boundary wall. The implementation mode is as follows: referring to fig. 2, distance values between each pixel point and the preset point are calculated, and when any distance value is smaller than a given distance maximum value, a pixel point corresponding to the distance value is displayed, so that a circular area is displayed on the boundary wall.
In one embodiment, the displaying any pixel point in the boundary wall when the distance value between the world coordinate of any pixel point in the boundary wall and the world coordinate of the preset point is smaller than a given distance maximum value includes: subtracting the distance value between the world coordinate of any pixel point in the boundary wall and the world coordinate of the preset point from the maximum value of the given distance to obtain a first difference value; when the first difference is smaller than zero, any pixel point in the boundary wall is not displayed; and when the first difference is larger than or equal to zero, displaying any pixel point in the boundary wall so as to display a circular area in the boundary wall.
Specifically, the distance value between each pixel point and the preset point is calculated, any distance value is subtracted from the maximum value of the given distance, the result is less than 0 and returns to 0, and the pixel point corresponding to any distance value is not displayed. And otherwise, when the result is larger than 0, displaying the pixel point corresponding to any distance value.
In an embodiment, the circular region includes a plurality of pixel points, and the smaller the difference between the pixel points and the preset point is, the larger the brightness of the pixel point is.
Specifically, the position of the circular area where the preset point is projected to is the center of the circle of the circular area. The circular area comprises a plurality of pixel points, and the smaller the difference value between the pixel point in the circular area and the preset point is, the larger the brightness of the pixel point is. That is, the difference between the pixel point of the center of the circle of the circular area and the preset point is minimum, and the pixel point of the center of the circle is brightest. The pixel points far away from the center of the circle are far away, the difference value between the pixel points and the preset point is larger, the brightness of the corresponding pixel points is smaller, namely, the brightness of the pixel points close to the edge of the circular area is smaller, and the corresponding pixel points are darker. As shown in fig. 2 and the above example, the closer the pixel point to the center of the circle in the boundary wall is, the brighter the pixel point away from the center of the circle is, and the closer the preset point is to the boundary wall, the brighter the pixel point in the circular area is.
In an embodiment, the circular region includes a plurality of pixel points, and after S106, the method further includes: acquiring a second difference value between any pixel point in the circular area and the preset point; dividing the second difference value by the given maximum distance value to obtain a quotient value; and assigning the quotient value to the opacity of the material ball to obtain the brightness of any pixel point in the circular area.
Specifically, the distance value between each pixel point and the preset point is calculated, the given distance maximum value is subtracted by any distance value, and then the given distance maximum value is divided by the given distance maximum value to obtain a result value, and the result value is between (0 and 1). Assigning the result value to the opacity of the material ball, so that the Alpha value of the pixel point closer to the center of the circle is higher, the Alpha value of the pixel point closer to the given distance maximum value is closer to 0, and the calculated value is closer to 0, and the color of the pixel point is more virtual.
If so, declaring a float type variable named TriggerToWallDistance as the shortest distance from the preset point of the triggering boundary wall to the plane where the boundary wall is located; a float type variable named MaxPrestance is declared as the farthest distance to display the boundary wall.
And obtaining the world coordinates of each pixel point in the material ball, further subtracting the world coordinates of TriggerPoint, and calculating the size of each obtained vector, namely the distance value from each pixel point to a preset point. And then, subtracting the distance value from each pixel point to the preset point by the MaxPrestance, converting the result by using a clamp material node, so that the result is 0 when the result is less than 0 and is MaxPrestance when the result is greater than the MaxPrestance, multiplying the result by the n-th power of (MaxPrestance/the distance value from each pixel point to the preset point), and finally obtaining recorded Alpha1, wherein the value of n can be adjusted according to the actual effect, so that the brightness degree of the displayed area is more obvious.
In one embodiment, S106 is followed by: obtaining the shortest distance from the preset point to the boundary wall; and when the shortest distance is smaller than the preset maximum flicker distance, starting the flicker of the boundary wall.
Preferably, after the starting of the flickering of the boundary wall, the method further includes: starting a time node and a trigonometric function node of the material ball; obtaining a time value through a time function of the time node; obtaining a period coefficient of a trigonometric function of the trigonometric function node according to the time value, the maximum flicker distance and the shortest distance; obtaining a flicker control value according to the trigonometric function and the periodic coefficient; and controlling the flicker of the boundary wall according to the flicker control value.
Preferably, the obtaining the periodic coefficient of the trigonometric function node according to the time value, the maximum flicker distance and the shortest distance includes: obtaining a third difference value between the maximum flicker distance and the shortest distance; calculating a ratio of the third difference to the shortest distance; obtaining the product of the time value and the ratio, wherein the product of the time value and the ratio is the period coefficient; the obtaining of the flicker control value according to the trigonometric function and the periodic coefficient includes: and taking the product of a trigonometric function sine and the periodic coefficient as the flicker control value, wherein the trigonometric function is the trigonometric function sine.
Specifically, the shortest distance from the preset point to the boundary wall is obtained, when the shortest distance is smaller than the preset maximum flicker distance, the Time node and the trigonometric function node of the material ball are used, the flicker of the boundary wall is started, and the shortest distance from the preset point to the boundary wall is used as the period coefficient of the trigonometric function, so that the shorter the distance is, the faster the flicker is.
For example, a float type variable, named Shining distance, is declared as the maximum flicker distance to start flicker. And declaring a float type variable named TriggerToWallDistance as the shortest distance between the trigger preset point and the plane where the boundary wall is located.
In the material ball, comparing ShiningDistance and TriggerToWallDistance by using if node, if TriggerToWallDistance > is ShiningDistance, returning to 1; if TriggerToWallDistance < shinning distance, then a time function in the ball of material is used, the time function will pass out a time value that goes on over time, say 2 seconds, and will pass out a 2. And the time value is multiplied by (ShiningDistance-TriggerToWallDistance) and then divided by TriggerToWallDistance to obtain the period coefficient. The periodic coefficient is multiplied by the sine function to obtain Alpha2, and the result Alpha2 changes periodically between (-1, 1) over time and changes faster and faster as TriggerToWallDistance becomes smaller. Therefore, according to the result of Alpha2, when the preset point is close to the boundary wall to the maximum flickering distance, the boundary wall starts to flicker, and the flickering speed is faster as the distance is closer, so that the warning effect is enhanced.
In one embodiment, the opacity of the material ball is assigned Alpha1 Alpha2, which allows the material of the boundary wall to be sufficient.
It should be noted that, when the UE4 engine implements the method for implementing the virtual intelligent boundary wall in the UE4 engine according to the foregoing embodiments, the declaration of each parameter refers to the following processing manner:
blue chart aspect: and (5) creating an Actor to add a static model component, wherein the static model component is a boundary wall model. A more cool bounding wall model may be provided, the material of which is modified according to the scofflaw above.
The fictitious self-contained function createDynamicMaterialInstance is used for converting the model material of the boundary wall into a dynamic material example, and the parameters of the material can be modified in a blueprint. Then, using the function SetVectorParamerValue to set TriggerPoin, using the function SetScalarPaeameterValue to set TriggerToWallDistance, MaxListance and ShiningDistance to define the parameters declared in the material in the blueprint.
In the embodiment of the invention, the world coordinates of each pixel point of the boundary wall are obtained from the material ball of the boundary wall, and the world coordinates of the preset points are transmitted to the material ball in the blueprint; calculating the distance values between the world coordinates of the preset points and the world coordinates of all the pixel points on the boundary wall in the material ball; and when the distance value between the world coordinate of any pixel point in the boundary wall and the world coordinate of the preset point is smaller than the maximum distance value, displaying the any pixel point in the boundary wall so as to display a circular area in the boundary wall. Therefore, the circular region can be displayed on the boundary wall, instead of displaying all the one boundary wall, and the boundary wall display having a more striking effect and a more warning feeling for the user can be provided.
