Problems with collisions

waldron

@landein207 i think its just a matter of getting used to how you set out code, il be less busy tomorrow if you wanted me to share a program demonstrating how to work with collision ?

landein207

Yes plz that may help me

landein207

Ok i was testing the controls with setspritespeed instead of setspritelocation the collision works but the movement looks like sliding in ice.
how can i avoid that effect in the movement?

I’ve never used setspritespeed, so I don’t know the exact way, but if you ’spritespeed *= 0.8’ at the end of your loop somewhere, that’ll work like friction..

landein207

I think i will open a new topic for that but thank you for the friction 'command'

If you decide to use setSpriteSpeed(), what you ought to do after the collision event happens is then stop the player from moving yourself.

setSpriteSpeed(player,150,0)
col = collideSprites(player,wall,false,false)
if col.exists then
setSpriteSpeed(player,0,0)
endif

@Jongjungbu that code setSpriteSpeed(player,150,0)
col = collideSprites(player,wall,false,false)
if col.exists then
setSpriteSpeed(player,0,0)
endif

It will make the player get stuck to the wall :P

Iv made a collision demo for you download code NDL89RND5U

@landein207

Well, I sort of simplified it. But maybe check out waldron's example :)

waldron

@landein207 the demo is pending but should be available soon.

landein207

Ok thanks for helping me understanding how collisions work here :)

pianofire

That has been approved

waldron

Lightning ⚡ fast :)

@waldron Express delivery!

Ok i just saw the code i understand how to make collisions with setplayerspeed now i think i will try see in another games with setspritelocation controls to see how to make collisions because im trying to make a game like undertale battle fan made that i think would be hard to play with a always moving character but thanks a lot now i know how to work with collidesprites + setspritespeed thank you all for helping me :)

waldron

@landein207 that's fine that demo was just to demonstrate collision for you. I can update the demo tomorrow to stop the player when not pressing the button and also add in another way to move the player without using the setspritespeed

landein207

Ok @waldron i was testing with the demo that you gave to me and i was trying to do the controls like this

loop
clear()
plr.show_collision_shape = true
wall.show_collision_shape = true
c = controls(0)
oldc = controls(0)

If c.lx == 0 and c.ly == 0 then
Setspritespeed(plr,0,0)
endif

If c.lx > 0 then
Setspritespeed(plr,100,0)
endif
If c.lx < 0 then
Setspritespeed(plr,-100,0)
endif
If c.ly > 0 then
Setspritespeed(plr,0,-100)
endif
If c.ly < 0 then
Setspritespeed(plr,0,100)
endif
If c.lx > 0 and c.ly < 0 then
Setspritespeed(plr,100,100)
endif
If c.lx < 0 and c.ly < 0 then
Setspritespeed(plr,-100,100)
endif
If c.lx < 0 and c.ly > 0 then
Setspritespeed(plr,-100,-100)
endif
If c.lx > 0 and c.ly > 0 then
Setspritespeed(plr,100,-100)
endif
//the rest of the code

but idk how this happens but looks that the diagonal one override the another one how does that work with out the diagonals override the rest of the controls?

waldron

@landein207 it's a different ball game when using the stick as it's very sensitive. there's also many ways to go about movement. Have a look at some of the sample programs in fuze and see how they ✋ handle movement.il update the demo tomorrow with stick controls

Richard

I think you want something like:

setSpriteSpeed (plr,100*c.lx,-100*c.ly)

Though 100 seems fast, but is in line with what you had.
