Hey, I'm building a level for my game, and as I am using tiles for the platforms on the level. I have player characters able to collide with the top and bottom of each tile; however, the characters can still go through walls through the left and right side on each tile. What are your guys' suggestions? Should I just try and add another collision event?

Player>Collision Event>ANY SIDE of Platform>Physical Response>1 1 0 0

Nope, didn't work =/ thx for the reply, though...

I think I nearly have it... I added a collision to each player, disabling them to hit any key if they hit the sides of the platforms, and re-enabling them to continue moving once they hit the top of the "ground" actor.

If anyone has any other suggestions, let me know...

The method i use for left and right collisions is to create to create three integer variables, 'speed', 'canright', and 'canleft'.
On keydown> right:

Code: Select all

x+=speed*canright;
canleft=1;

and on keydown> left

Code: Select all

x-=speed*canleft;
canright=1;

and on collision > left side of platform

Code: Select all

canright=0;

and on the right side

Code: Select all

canleft=0;

Now the reason for 'speed' is so you can give the player a speed powerup at anytime without having to go back and change all these scripts. Usually I set 'speed' to 4 and canright and canleft both to 1 on player>createactor.

So when a player runs into a wall or platform, his xvelocity in that direction is reduced to 0; and all he has to do to reenable it...is push the other direction. I used this method in Gauntlet (on the demos page).

The script in this post has changed from the gauntlet script in that i've used '*' instead of 'if'. Its less code and less work for the cpu.

If you try it you'll notice that this gives a very solid left and right collision; and the player doesn't 'bounce' off the wall, nor does he 'stick' to it. Hope this helps.

Btw, this happen to filled region also...
ummm...walrus, are you sure make the collision event to be repeated???
