Topic: [Coding] Check for collision between to points on map?

Hey guys,

I'm trying to check if there is a wall(or some other collision) between to points on the map.
My problem is, that >Hit< stays false in the following code, even if there is a collision between the two points.

My code:

            float Dist = pos2distance;
            bool Hit;
            Hit = false;
            for (int i = 1; i < Dist; i += 32)
            {
                vec2 TestPos = pos1 + normalize(pos2 - pos1 ) * i;

                if (Collision()->GetCollisionAt(TestPos.x, TestPos.y)&CCollision::COLFLAG_SOLID)
                {
                    Hit = true;
                }
            }

Would be great, if somebody can help me with that! Thanks!

Try using

int CCollision::IntersectLine(vec2 Pos0, vec2 Pos1, vec2 *pOutCollision, vec2 *pOutBeforeCollision)
Real programmers don't comment their code - it was hard to write, it should be hard to understand.

Re: [Coding] Check for collision between to points on map?

Thanks, but it does output an error at compiling:

src/game/client/components/aimbot.cpp(143): error C2664: "int CCollision::Inters
ectLine(vec2,vec2,vec2 *,vec2 *,bool)" : Konvertierung von Argument 3 von "const
 float" in "vec2 *" nicht möglich

Free translated:

src/game/client/components/aimbot.cpp(143): error C2664: "int CCollision::Inters
ectLine(vec2,vec2,vec2 *,vec2 *,bool)" : converting of Argument 3 from "const
 float" to "vec2 *" not possible

My code:

            vec2 pOutBeforeCollision;
            vec2 pOutCollision;
            Hit = Collision()->IntersectLine(OwnPosition, AimPosition, *pOutCollision, *pOutBeforeCollision, false);

Re: [Coding] Check for collision between to points on map?

should we really help someone who is trying to write a client sided aimbot?

aimbot.cpp(143)

Well I don't care. Learn how to work with pointers.

Hit = Collision()->IntersectLine(OwnPosition, AimPosition, &pOutCollision, &pOutBeforeCollision, false);

If you don't need the two positions just do:

Hit = Collision()->IntersectLine(OwnPosition, AimPosition, 0, 0, false);

If I saw this correctly you still have to check "Hit" against "Collision::COLFLAG_SOLID" after that line as it only returns "GetCollisionAt(...)".

Re: [Coding] Check for collision between to points on map?

Dude thats what I expected. I'm not working on an aimbot, trust me. Just look my previous posts! Im creating a POI system. I'm work ing on a base of a aimbot, thats true. I just have not got the knowledge to create such a file by myself.
Aimposition is btw the position where you're aiming.

In the end it should not be possible to move the POIs(small flags) thought walls.

That's still developing into some sort of tutorial (or tips at least) on how to make a cheat, and that's not tolerated here. Closed.
