How can I detect if a unit collides with a terrain or trees?

[Nastyan]

So basically, I wanted to create a simple dash spell but I want the caster to pass through units but not through trees and cliffs.

Is there a way to do that in GUI?

 

[Devalut]

I check pathability in my resource Teeth so that each projectile doesn't continue if it collides with trees, ravines, cliffs, or destructibles.

And for destructibles

Thanks, I got it now.

One more thing, what should I do once the caster collides with a terrain or destructable? I'm fairly new to making things in MUI and I've only done those generic MUI dash where I just turn the collision off and on but this one is kind of confusing me Should I just de-index right away?

Limit is your imagination, make some fiery explosion or polymorph nearby enemies.

I do not understand, perhaps posting your trigger would be more direct.

Sorry about that, and I apologize if I took long to respond, I've had a headache The whole day yesterday and I had to rest (Its 5AM here)

SO anyways here are the triggers.

The Caster dashes to the target point, phasing through units only but instantly stops when colliding with destructables and cliffs or ravines.

Init

Spoiler

• Bruiser Init
  • Events
    • Time - Elapsed game time is 0.01 seconds
  • Conditions
  • Actions
    • Set BruiserW_index = 0
    • Set BruiserW_dash_speed = 40.00
    • Set BruiserW_dash_collision = 32.00

Cast

Spoiler

• BruiserW Cast
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Dash

I'm not really good at this but here's the looping.

How dare you have a life you ungrateful wretch, I demand instant responses from my vietnamese basket weaving forum peers.

In your periodic try and make the conditions for a "dead-end", i.e. when the spell is going to fail and de-index, try to use only instance.
If you must use an additional "if then" block then use a variable that can act as a flag for de-indexing, in my Teeth resource I do this with the variable called TeNe_distance, if the projectile hits a tree I set the distance to 0.00 instead of adding another de-indexing block, because when the loop fires a second time the de-index condition will catch that distance is 0.00 and know to de-index that instance.

The result allows your trigger to be readable, not only to others but yourself, and that leads to a cleaner thought process.

Thank you, it does look cleaner and more readable, i think I get it now and also i will be checking the link you posted.

Examination week is nearly over I would resume what I was doing after the exams are finally over. Ill be back here if things doesnt really right thanks
