[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] This invention provides a method for deploying NPCs in a virtual reality game, such as... Figure 1 As shown, the method includes the following steps:

[0033] S102, Build the deployment interface in the UE4 blueprint to obtain the virtual reality scene model;

[0034] You can use UI components to build a deployment interface in a UE4 blueprint, and you can also deploy different NPCs based on different users' choices. A specific deployment interface can be built as follows: Figure 2 As shown.

[0035] NPC is a gaming term, short for non-player character. It refers to a type of character in a game that is not controlled by a real player.

[0036] In one embodiment, such as Figure 3 As shown, the deployment interface can be divided into three parts: the deployment bar on the left, the overhead map in the middle, and the deployment bar on the right.

[0037] The deployment bar on the left can be used to deploy different NPCs, such as helicopters, fighter jets, and reconnaissance aircraft, according to the user's selection. After deployment, the corresponding NPC deployment bar will enter a cooldown period.

[0038] The overhead map in the middle displays the NPCs deployed by the user as icons, and allows the user to select a spline path (as shown in the middle of the map) for the NPCs to fly along. The deployment panel on the right displays the NPCs the user is currently deploying and allows for setting limits on the number of NPCs.

[0039] S104, Draw a spline and generate the corresponding NPC at the starting point of the spline so that the NPC moves with the coordinates of the spline;

[0040] Specifically, the required spline pattern can be drawn through program code. When the required spline pattern is circular, the AddPoint function is used to add spline points to the spline, allowing the spline to rotate and change angles according to the points. The code is executed 9 times to add 9 points to the spline (because each point adds 36° upwards, so 9 points can form 360°, which is exactly a circle). Then, the radius of the circle is determined by the starting point of the spline and the position of the center of the circle, thus drawing a circular spline.

[0041] S106, periodically return the location of the NPC in the scene to the delivery interface; specifically, you can choose to return the location of the NPC in the scene to the delivery interface every 0.1 seconds.

[0042] S108: After receiving the data, the deployment interface converts the 3D coordinates of the NPC in the scene into 2D coordinates to deploy the NPC.

[0043] This includes converting the 3D coordinates of the NPC's location in the scene to 2D coordinates, including:

[0044] Get the pixel size (X, Y) of the NPC icon;

[0045] Measure the length and width of the virtual reality scene, and divide the pixel size of the NPC icon by 2;

[0046] Subtract the actual coordinates of the NPC's location from the scene length, and then multiply by the 2D map's aspect ratio on the screen to convert the 3D coordinates of the NPC's location into 2D coordinates.

[0047] After completing the above steps, you can achieve the following: Figure 4 The interface shown is the effect of deploying NPCs.

[0048] In one embodiment, please refer to Figure 5 The present invention also provides a system for placing NPCs in a virtual reality game.
