I've been tinkering around with the "matrix example" that came with DBPro software. I'm in a process of making a 3d Rpg game thats finds yourself inside an active volcano/mountain with lava flowing threw its caverns. With the help of the matrix example, I was able to make the lava have the look of a flow rythm like waves of the ocean.

My question is, My main character can go threw this flow of lava without damaging its health. I need to add some kind of collision detection whenever my character touches the lava to decrease its health or an instant kill.

How do I do that?

I'd say place a hidden plane on the lava so when your character collides with that it's easier to tell, I don't know any method for colliding with certain parts of the matrix. If the lava is actually just a whole separate matrix then have damage apply when he touches that matrix.

I hope I made some sense!

I've thought about making an invisable object like a cyclinder or your idea "a plain" to where the lava is place and when my character touches it, it'll decrease health points. Works fine now. Thanx for your input

Try using GET GROUND HEIGHT on the matrix, then plugging in your player's X and Z coordinates. Then just check if your player's Y coordinate is above or below the matrix.

Maybe something like this:


You could even offset the Y coordinate by half of the player model's height downward (if its origin is in the middle) to detect if the player's feet are in the lava.

<-- Spell based team dueling game!
