Proper collisions!?! Help!

Erg. That's all I can think. Erg. Wibble wibble wibble...

Does anyone have any idea how to solve my problem? I want my players to bounce off walls (not just reversing the direction, but bouncing like a cue ball off the sides).

My collisions are set up as follows:

Const car_col=1
Const world_col=2

Collisions car_col,world_col,2,1

(Note: I am using the Stop response so that Blitz doesn't try to automatically move the cars up or down)

Then I look for collisions and try to correct them:

If EntityCollided(c\mesh,world_col) ; PLAYER VS LAND

xnorm#=CollisionNX(c\mesh,1)
ynorm#=CollisionNY(c\mesh,1)
znorm#=CollisionNZ(c\mesh,1)

c\vx#=c\vx#+xnorm#
c\vz#=c\vz#+znorm#

MoveEntity c\e,c\vx#,0,c\vz#
ResetEntity c\mesh

End If

This appears to work at a slow speed, but if my car heads straight for a wall quite often it just cruises on through it bobbling slightly... can anyone help? I really want to try and get some nice collisions in my game but (to be honest) I am no mathematician!!

Thanks in advance!

might sound silly, try instead using True not 1. i had nuber of problems using 1 and true. Shouldnt really matter, but the results were different

1 and true should mean the same thing or that's a bug!

i know, 1 and true seem to mean different things for my programs, so i stick with true. it could be a bug

If not(true=false) then
true=true
else
true=1
end if

Confused? I don't even think I'm using true in the collision script! Argh! Brain hurt. Must lie down.

Thx anyways!
