It would help if the Mexican looked for a Trrump type object instead of another Mexican.

It's not working like that. Please do this:

public void die()
{   
    if(getOneIntersectingObject(Trump.class)!= null)
    {   
        vSpeed =-50;
    }
}

On line 62 (of the Mexicaan class) you have Mexicaan.class as the parameter, there is no Trump involved (besides for the name of your instance of Actor). You also just change the vSpeed in that method no actual death.

Thats what he wanted to do. Well more or less. I dont know if you can call that flying.

@yehuda i changed the vspeed to -50 which causes him to go up and in line 91 the mexican gets removed if it hits the top of the world

It has to work. Try removing the Mexicaan as soon as he hits Trump instead of changing the vSpeed value . If that works then it has something to do with your moving mechanic. Sorry im too tired to read into that.

well its not, maybe worth noticing: if the mexican is still in the air and not on the ground, the code works he goes flying in the air and disappears if trump touches but once he lands he doesnt move. AND OMG I FIGUERED IT OUT WHILE WRITING THIS. the problem is in line 41, the vspeed is 0 when it touches the ground so it stays 0 the whole time, i had to call die(); after it so it would work. thanks so much for all your advice and support i really appreciate it. :)

Yea I knew it was somewhere else in the code, sorry that im a lazy fuck when I'm tired c: Glad you found it yourself^^

#

But in your given code the 'die' method is called after 'checkFall', and 'moveAround' is called right after 'die' (calling 'atWorldEdge' on line 24 doesn't do anything), so line 41 should not have been executed.

#

It gets executed (answering my own question) because you have to go through an extra act cycle since changing the 'vSpeed' doesn't actually have an effect until the 'fall' method gets called. To fix the problem in the code shown above you can just add in "fall();" on line 67.

Scenarios

trump should collide with mexicaan and send him flying out of the map, the only problem is that trump goes straight through mexicaan and cant seem to "see" him
