This week I show off my newly completed collision detection algorithmBro. which I use to render my entity, from Vector3f of the LWJGL library, and Jbullets Vector3f. Opengl Game development log videos with commentary about my indie 3D RPG java game.
#Java lwjgl how to entity collision 3d detection update
Here is some of the code I use for the current collision: public boolean collision(Entity e1, Entity e2) Īs for the update tick regarding collisions: for (int i = 0 i < collidables. Java 3D collision detection with JBullet. Most of the code is based on ThinMatrix tutorial on YouTube, except some of it which I have created myself. 100% accurate collision would be to use some form of collision detection for each triangle, but there are so many and therefore, the game will lose it's performance. I would like to have the ship collide with the enemy. The Ship.java class draws a square and then you can move the square around. Below I have included the two java classes that I am working with. I am using blender-models and they consist of triangles. Im new to LWJGL and need help with collision detection. I am trying to implement frustum culling in my 3D Game currently and it has worked efficiently with the entities because they have a bounding box (AABB) and its easier to check a box against the frustum. The collision code thinks the ball is a rectangular box, so the ball often collides with a brick even though the ball. OpenGL (LWJGL 3) culling terrain vertices/triangles that are not in the view frustum. Because the ball is a circle-like object, an AABB is probably not the best choice for the ball's collision shape. I already have a system for collision with the terrain, but it cannot be used to collide with entities(since the terrain only has height to collide with). Let's see if we can figure out a more precise collision detection technique. I have worked on a system, but it is not really good.

I am trying to make a 3D game, but I am having a hard time with the collision. Although, this just creates a 3d bounding box around the object, rather than 3d convex hull, which probably should be used.
