Collision checking?

[Guardian69]

Hi guys

I have two actors that require collision. One is the player actor and the other is a scenery actor.

I want to be able to check if an actor can move into a space before they do. Ideally I would use a function to check the proposed 2d vector and return a Boolean value that identified if it was occupied.

Does such a thing exist? If not how would I set one up?

Cheers,

they have a function called collisionfree that does just that.

Ah awesome! Thank you!

"CollisionFree: Check if position (x, y) is collision free for ActorName. Return 1 if not collide, 0 otherwise."

So if I am using the following script in my players draw event, how would I get the player actors next x and y?

"yvelocity = yvelocity + 1;
xvelocity *= .95;"

i dont know im not an expert on it. ask Hblade hes a good coder.

The actor's next position will be (x+xvelocity, y+yvelocity) assuming you have already changed xvelocity and yvelocity (after this part).

Code: Select all

yvelocity = yvelocity + 1;
xvelocity *= .95

If not, you position will be (x+xvelocity*0.95, y+yvelocity+1).
