New to AGD, vhelp me with colliding boulders

[gazj82]

Started making a clone of Pickaxe Pete for the Phillips G7000 using AGD. This is my first go with AGD!

I need the rocks which are sprite type one to detect when they collide. If I put this bit of code in they just detect there own selves and die immediately.

Anyone know a way round this.

At the start of the sprite event you could try this:

LET TYPE = 255

To temporarily change the current sprite to a different type so the collision code won't pick it up. Do your usual processing then finish by setting the type back at the end:

LET TYPE = 1

That sounds good, I'll give it a try. Just discovered 4.1 after starting on v3. So I may have a restart to take advantage of new features.

Thanks for your help and a great tool! Ever thought of doing a C64 version?

[Jonathan Cauldwell]

Looking at the code again, I don't think the solution I gave you will work properly. If it doesn't work, try replacing LET TYPE = 255 with

ASM 221
ASM 54
ASM 0
ASM 255

and LET TYPE = 1 with

ASM 221
ASM 54
ASM 0
ASM 1

Be extremely careful how you type these in!

As for a C64 version, it would take me too long to convert AGD to a machine with a different processor inside. However, if an experienced developer were to volunteer I'd be very happy to provide every assistance.

Hi Sorry, for the delay in getting back to you on this. I only get a few hours a week to work on this and it has taken me this long to rewrite for v4. Unfortunately your methods above don't seem to work. Anymore ideas?

[Jonathan Cauldwell]

After a bit of investigation I've concluded that there's a problem with the way the COLLISION command compiles in AGD 4 so I'll have to address that.

The ASM commands should be okay in AGD 3.5. They'll also work for the CPC version.
