[Nice 2 Have] Collision - Slide wall

I don't know how you want us to report you bugs or nice to have things ?

When you are "colliding" with a wall at less than 90degrees, you should slide alongs it.

The algo for this is easy (something like this) :

Code:: position.X += velocity.X; if(colliding()) position.X -= velocity.X; position.Y += velocity.Y; if(colliding()) position.Y -= velocity.Y; position.Z += velocity.Z; if(colliding()) position.Z -= velocity.Z //colliding definition : bool colliding() { int minX = Position.X - size.X / 2; int minY = Position.Y - size.Y / 2; int minZ = Position.Z - size.Z / 2; int maxX = Position.X + size.X / 2; int maxY = Position.Y + size.Y / 2; int maxZ = Position.Z + size.Z / 2; for (int x = minX; x <= maxX; x++) for (int y = minY; y <= maxY; y++) for (int z = minZ; z <= maxZ; z++) { if(blockType[x, y, z] != 0) return true; } return false; }
