Forums » Help » Managing fake collisions

Hi there,

i would like to create a function in my main.js which is able to manage "collisions" between my entities. I call it fake collisions because my entities just go from a position to another position, they dont have any speed/velocity and collisions properties are useless then.

the idea behind this function would be like comparing two positions on the Y axis (or X) and decide how entities would react.

but my game is a tetris like, so among those two entities one doesn't move and one is falling.

the difficulty is to make act these entities like if they were colliding.

Sounds like what you want to do is move blocks instantly but only if you know beforehand that a collision will not take place in doing so.

Should be easy enough to do. Assuming you're only talking about entity-to-entity collisions, you can use Entity.distanceTo to figure out how far away a given block is.

So assuming also that your blocks move a constant distance each time, you should be able to tell if the next move will be close enough to collide.

Thanks a lot, i did some research about this method and i think it will do the job ;)
